AUTOMATIC CHARGING MODE
When an Automatic Charge is performed, the charger switches to the maintain
mode automatically after the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging
aborts, the charger's output is shut off and the Clamps Reversed/Bad Battery
(red) LED will light. Do not continue attempting to charge this battery. Check the
battery and replace, if necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort and the
Clamps Reversed/Bad Battery (red) LED will light.
COMPLETION OF CHARGE
Charge completion is indicated by the Charged/Maintaining (green) LED.
When lit, the charger has switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the Charged/Maintaining (green) LED is lit, the charger has started
maintain mode. In this mode, the charger keeps the battery fully charged by
delivering a small current when necessary. If the charger has to provide its
maximum maintain current for a continuous 12 hour period, it will go into abort
mode (see Aborted Charge section). This is usually caused by a drain on the
battery or the battery could be bad. Make sure there are no loads on the battery. If
there are, remove them. If there are none, have the battery checked or replaced.
MAINTAINING A BATTERY
The SC1355 maintains both 6 and 12 volt batteries, keeping them at full charge.
NOTE: The maintain mode technology allows you to safely charge and maintain a
healthy battery for extended periods of time. However, problems with the battery,
electrical problems in the vehicle, improper connections or other unanticipated
conditions could cause excessive current draws. As such, occasionally monitoring
your battery and the charging process is recommended.
